Use this auto loan calculator to determine how much extra you need to pay each month to pay off your auto loan early. Learn the best strategies to save money and time on your auto loan.
How to Use This Calculator
Enter your current auto loan details into the calculator on the right side of this page. The calculator will show you:
- Your current monthly payment
- How much you'll save by paying off early
- The total interest paid over the life of the loan
- A breakdown of your payment schedule
You can adjust the payment amount to see how quickly you can pay off your loan. The calculator will show you the new payoff date and total interest saved.
Formula Used
The calculator uses the standard auto loan amortization formula to calculate payments and interest:
Monthly Payment (PMT) = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (APR/12)
- n = Number of payments (loan term in months)
The calculator also calculates the total interest paid by comparing the total payments to the original loan amount.
Strategies to Pay Off Your Auto Loan Early
1. Make Biweekly Payments
Paying every two weeks instead of monthly gives you an extra payment every year. This can significantly reduce your payoff date.
2. Increase Your Monthly Payment
Even small increases in your monthly payment can add up to substantial savings over time.
3. Pay Off Extra Principal
If your loan allows, pay extra principal each month to reduce the principal balance faster.
4. Refinance Your Loan
If interest rates have dropped, refinancing can lower your monthly payment and payoff date.
5. Use Windfalls
Apply tax refunds, bonuses, or other windfalls to your loan balance when possible.
Worked Example
Let's say you have a $20,000 auto loan with a 5% APR and a 48-month term. Your current monthly payment is $461.44.
If you increase your monthly payment to $500, you can pay off your loan in 39 months instead of 48 months, saving $1,440 in interest.
| Scenario | Monthly Payment | Payoff Date | Total Interest |
|---|---|---|---|
| Original Payment | $461.44 | 48 months | $1,440.00 |
| Increased Payment | $500.00 | 39 months | $1,440.00 |
This example shows how even a small increase in payment can significantly reduce your payoff date.
Frequently Asked Questions
How much can I save by paying off my auto loan early?
The savings depend on how much you increase your monthly payment. Even small increases can add up to significant savings over time. Use the calculator to see exactly how much you can save.

Both strategies can help pay off your loan early. Biweekly payments give you an extra payment each year, while paying extra principal reduces the principal balance faster. The best approach depends on your specific situation.

Yes, many auto loans allow prepayment without penalty. Check your loan agreement to confirm, but in most cases, you can pay off your loan early without fees.
